Students read how to determine the total impedance of a parallel circuit using complex numbers. The "J" term is used in the calculations.

In this animated object, learners examine how current, voltage and the discharging capacitor of a series RC changes during 5 time constants. A brief quiz completes the activity.

In this animated object, learners study the operation of a linear voltage differential transformer. A brief quiz completes the activity.

Learners examine the basic elements of a machine vision system. A short quiz completes the activity.

Learners read how to use a lumber rule to quickly and accurately estimate board feet. They then use virtual samples to practice the process.

Learners view videos of law enforcement and corrections officers describing their jobs and the opportunities in their fields. Because this object contains large video files, it is best viewed using a high band width connection. Low band widths will result in longer download time and video delays.

Learners review Ohm's Law and then work 12 problems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and are asked to solve for the third.
